Individual Therapy for Partner Betrayal Trauma in Portland

Specialized Individual Therapy for Partner Betrayal Trauma in Portland


You’ve been rewriting the story of your relationship in your head, trying to figure out which chapters were real.

The long weekend at Cannon Beach where they seemed so present, had it already started? The nights they said they were working late at the office in the Pearl, were they?

You keep recalculating and every answer pulls the rug out from under you a little further. You were building a life with this person in Portland, maybe in Sellwood, maybe in Lake Oswego, and the fact that you didn’t see it shakes something deeper than the betrayal itself: your ability to trust your own perception of anything.

Now ordinary moments have a charge they didn’t used to carry: their phone buzzes and your body reacts before you can think, they mention a coworker and you’re scanning for tells.

The restaurant on Division where you celebrated your birthday, the coffee shop on Alberta where you used to meet on Saturday mornings, your brain can't go to those places without reopening the question of what was real and what wasn’t. So you take different routes, skip the places that used to be yours, because every familiar spot pulls you back into the recalculating.

Images keep intruding, scenes your brain assembled from whatever details you have. They show up while you’re in a meeting, while you’re crossing the Burnside Bridge, while you’re trying to be intimate. Some days you can’t stop seeing them, and other days everything goes flat and you sit through an entire dinner without really being there.

The detective work has consumed you: checking their location, reading old messages, analyzing everything they say for cracks in the story.

Your body has been registering all of this too, teeth grinding, stomach problems, headaches, sleep that barely counts.

The person who made decisions confidently, who enjoyed a walk on Hawthorne or through the Saturday Market without their mind somewhere else, that person feels unreachable.

You may have tried therapy with someone in Portland or Beaverton who helped you understand the “why,” but understanding hasn’t changed what your body does every time their phone lights up.

What Life Looks Like After Partner Betrayal Trauma Treatment


Research from the University of Oregon shows that betrayal by someone you depend on creates a specific kind of damage that other traumas don’t.

It disrupts your ability to trust your own perception, your capacity for closeness with other people, and even your physical health.


Here’s what my clients describe after 1–5 sessions, once that damage starts to reverse:

You trust your own judgment again. You make a decision about your marriage, your finances, or your living situation and you don’t need to run it past three friends and your sister to make sure you’re not crazy. The fog of “what if I’m wrong about everything” lifts, and you can see your options clearly enough to choose one.

You’re present with the people who matter to you. You sit on the floor and play with your kids without your mind drifting to the affair. You meet a friend for dinner in Sellwood and you’re in the conversation instead of pretending that you’re fine. If you’re rebuilding the relationship, you can have a difficult conversation with your partner without your nervous system preparing to fight, or shutting down. If you’re divorcing, you can co-parent a Saturday morning without spiraling afterward.

Your body stops keeping score. The jaw clenching, the stomach problems, the tension headaches, the 3am wakeups with your heart pounding: those are your nervous system responding to an old threat, not what’s happening. When the trauma resolves, your body follows. You sleep through the night, you eat a normal meal, and you wake up thinking about your day, not about what your partner did.

You get your professional life back. You sit through a meeting at Nike, or a client call at your office in the Pearl, and your mind stays in the room. You write the brief, finish the project, see the patients. The hours you were spending on obsessive investigating and mental replay open back up, and you use them to do your job, build your business, or figure out what’s next.

You start making plans again. You book the trip to Bend. You look at condos in Multnomah Village. You start the conversation with the attorney, or with your partner, or with yourself about what you want your life to look like. The future stops feeling like a looming threat, and starts feeling like something you have the power to shape and influence.

ART is an investment in your freedom, mental health, and overall well-being.

Half-Day Intensive: $2,500

Up to 4 hours of focused treatment in a single session, plus follow-up check-ins at 2 weeks and 30 days. This is the format most betrayal trauma clients need. The extended time gives us room to work through everything without stopping mid-process.

For comparison: 6-12 months of weekly therapy runs $3,600–$12,000+, most of it spent processing the story of what happened rather than putting a stop to the nightmares, the anxiety, and the intrusive thoughts/images.

Not sure if ART is right for your situation?

Book a single session first ($500, 90 minutes). This isn’t a shortened version of treatment; it’s a chance to experience the process and make sure we’re a good fit before committing to the intensive. If you move forward, the $500 gets credited toward your intensive cost.

About Allyson Clemmons, LICSW
Portland Partner Betrayal Trauma Therapist

My specialization in partner betrayal trauma emerged from years of treating affairs as a couples therapist. While couples work was essential for the relationship, I noticed betrayed partners also needed specialized individual therapy that wasn’t available. They would only find generic trauma treatment that kept them talking in circles for months, while their nervous systems remained hijacked by the betrayal.

I noticed that partner betrayal creates a specific type of trauma that requires targeted treatment. The neurological impact is profound, and it doesn’t resolve through insight or understanding alone.

Now I exclusively use Accelerated Resolution Therapy to help people move from obsessive investigating and constant triggering to genuine peace in just 1-5 sessions. You don’t need to manage partner betrayal trauma indefinitely. You can actually resolve it.
